Sibjotang Increases Atrial Natriuretic Peptide Secretion in Beating Rabbit Atria

Figure 4

Concentration-dependent effects of Sibjotang (SJ) on ANP secretion, pulse pressure, and stroke volume in atria. (a) Effects of SJ on ANP secretion. (b) Effects of SJ on pulse pressure. (c) Effects of SJ on stroke volume. Values are mean ± SE. Number of experiments: SJ (0 μg/mL, control), ; SJ (60 μg/mL), ; SJ (100 μg/mL), ; SJ (300 μg/mL), ; and SJ (1,000 μg/mL), . , versus mean values of two fractions before SJ; , versus control.
